Pengaruh Level Protein, Vitamin A dan Vitamin E terhadap Pertambahan Bobot Badan dan Beberapa Fungsi Reproduksi Tikus Putih (Rattus norvegicus)
Abstract: Protein has the role
in the development of physiological structure and body immunity system.
Reproductive hormones, gametogenesis and fetus development are very much
affected by the content of protein, vitamin A and E. Vitamin A is known to have
a role in the integrity of epithel tissue, thus it has a great effect on the
process of gametogenesis and embryogenesis. Vitamin E is recognized as an
anti-sterility vitamin because of its important role as an intercellular
antioxidant, in absorbing and storing vitamin A. This research was intended to
determine the effect of protein content (15%, 18% and 21%), vitamin A (2000
IU/kg of feed), and vitamin E (30 mg/kg of feed) on body weight and some
characteristics of reproduction of white mice (Rattus novergicus). The
reproduction characteristics observed on female were the litter size and their
body weight at birth, whereas those on male were fertility and morphology of
spermatozoa. The research results showed that there were some effects of
protein, vitamin A and E on increased body weight of female. The best result
with a significant change (P<0.05) was with treatment of 18% protein with
vitamin A (32.00±5.32 g/week) and 15% protein with controlled (30.25±2.29
g/week). The increased body weights of female and male were respectively
24.45±4.52 and 25.54±1.83 g/week. However, other characteristics did not
show any significant change. In all treatments, male were able to mate with
female and make them pregnant. The morphology of spermatozoa showed a long
curved head with a long tail.
